When it comes to Consumer Reports’ latest tests of all-season and winter replacement tires, Michelin and Continental lead the way. However, tests revealed that worthy tires were not difficult to find and many provided good overall performance.

The Michelin Defender led all T-speed-rated all-season tires tested. It has excellent tread life and scores highly in three-season driving tests (dry braking, wet braking, handling and hydroplaning). It was followed closely by the Continental ProContact EcoPlus. These tires are well-suited for many older cars, minivans and small SUVs.

A number of newer vehicles come with H- and V-speed-rated all-season tires, which Consumer Reports categorizes as performance all-season tires. In the performance all-season H-speed-rated category, the Michelin Primacy MXV4 was its top-rated model, with the Continental PureContact close behind. The Michelin performed well in most weather tests, offers a comfortable, quiet ride and has low rolling resistance. The Continental was impressive in the wet-braking test and has a good balance of all-weather performance and tread life.

Another Continental PureContact model led the performance all-season V-speed-rated group, followed closely by the Pirelli Cinturato P7 All Season. The Continental is an all-around good performer. The Pirelli gets top marks for handling, but its tread-life score was just fair.

Many of the 62 all-season tires scored well in the three-season driving categories, and several models performed well in snow traction and ice braking.

Almost all of the winter tires proved excellent at snow traction, and most were good to excellent at ice braking. Winter tires are desirable in places with moderate to severe snow and ice conditions. Michelin’s X-Ice Xi3 and Xi2 tied for the lead in Consumer Reports’ test of 16 winter tire models. The Xi3’s excellent rolling resistance set it apart, but the similar Xi2 performed better in handling.

Consumer Reports tests each tire for the following: wet, dry and ice braking; handling; hydroplaning; snow traction; ride comfort; noise; rolling resistance; and tread life to determine an overall score. All tires tested were size P215/60R16 to fit the test car, a Chevrolet Cruze. Consumer Reports expects that other sizes of the same tires would provide similar performance.

Consumer Reports offers the following advice:

•Buy only the best. Investing in better tires can give you a wider margin of safety when driving. A little extra grip, for example, can mean the difference between an accident and a close call.

•Stick with the speed rating. T-speed-rated tires are made to sustain a maximum speed of up to 118 mph, and H- and V-speed-rated tires are designed to withstand 130 and 149 mph, respectively. For the typical driver, such speeds might seem outlandish, but speed ratings also reflect how well a tire dissipates heat, which affects overall quality and durability.

•All-season tires. Best choice for year-round traction, long tread life and a comfortable ride. But they often lack the precise cornering grip and handling of performance all-season tires.

•Performance all-season tires. Best choice for improved handling and cornering grip, compared with standard all-season tires, without giving up too much comfort and wear. But many have lower tread-wear warranties.
